1.5 Creating Part Features
Created features
The Create Part Feature function can be used to create features that
are not found on the part geometry. These features can be used as
reference points for inspection purposes. For example, in order to
measure a feature that is referred to a point off the part geometry, the
user could create the reference point.
Users can create points, lines, circles, distances, angles, and part
skews. Created features are the same as probed features except that
the created features are geometrically perfect, so form error and
tolerance values do not apply.
Created features are not the same as constructed features, which are
discussed in the next section of this chapter. Created features are
defined by the user. For example, to create a circle, the user defines
the location of the center point and the diameter or radius.
Constructed features are built from previously measured or created
parent features. For example, the user could construct a line between
two or more points in the feature list. Constructed features can have
form errors and tolerance values.
